John, as of right now, I have just "successfully" built XSPEC for Lion, with the patch applied that Matt pointed me to for Python. I had no errors in the build, and I'll attempt to use it shortly and let you know off-line if anything fails. Cheers, Eric The other problem is that XSPEC doesn't do 64-bit builds on Mac because of X11, or so they say. If you can get it to work please let me know. I tried this earlier this week with no luck.

I made the patch and am trying to rebuild. Thanks! Eric Matt wrote: Hi Eric, Looks like this is known for non-framework builds of Python on OSX. (We don't build it Framework-wise because it caused a bunch of problems in the past and mainly only allowed usage of a few native widgets.) Here is a patch you can apply and then rebuild Python with to (possibly) get it to work: http://bugs.python.org/issue1602133 -Matt On Fri, Aug 24, 2012 at 4:46 PM, Eric Hallman <hallman13@gmail.com> wrote: Hello, I know this is not a yt specific issue, however it involves an interaction of the yt installed python and XSPEC. Maybe some of you on this list have done an XSPEC install on Mac OS X (Lion in this case) and run into this. At link time during the build of XSPEC, it gives the following error: Undefined symbols for architecture x86_64: "_environ", referenced from: _initposix in libpython2.7.a(posixmodule.o) ld: symbol(s) not found for architecture x86_64 Originally on my Mac, XSPEC tried to build 32-bit, and failed with python linkages (since python is 64 bit in the yt install build). Once I went to 64-bit, this was the only remaining error. Does anyone have ideas? Thanks!
